Abstract
Provided is a variable magnetic flux-type permanent magnet rotary electric machine wherein a leakage magnetic flux leaking from a certain permanent magnet included in the rotor core to a permanent magnet circumferentially adjacent on either side of the certain permanent magnet is controlled by q-axis current and thereby a magnetic flux emanating from the certain permanent magnet and linking with the armature coil wound on the stator is controlled without forming a mechanically weak part in the rotor core.
